Jamal placed two orders with an internet clothing store. The first order was 13 ties (t) and 4 pairs of suspenders (s), and totaled $487. The second order was for 6 ties and 2 pairs of suspenders, and totaled $232. The bill does not list per-term price, but all ties have the same price and all suspenders have the same price

Answer:

t = $23

s= $47

Explanation:

First order =

13t + 4s = 487

Second order

6t + 2s = 232

13t + 4s = 487 (1)

6t + 2s = 232 (2)

Multiply (2) by 2

12t + 4s = 464 (2b)

13t + 4s = 487

12t + 4s = 464

Subtract

12t - 10t = 487 - 464

t = $23

Substitute t = 23

13t + 4s = 487

13(23) + 4s = 487

299 + 4s = 487

4s = 487 -299

4s = 188

s = 188 / 4

= 47

s= $47
